I install a new one every oil change.

To replace the old one? 52000 miles and only on second washer and that was only because I installed a mag drain plug. Nary a drop leaked. Maybe it's a combination of KIPASS and the Lucas full syn. I run

I do check it each time I change the oil.

They cost something like 30 cents each...... why wouldn't you change it?

I agree, it is probably not necessary to change each time, but for a few cents I know I get a good seal each time. You could probably use the original one for a long time and have no trouble, just something I prefer to do.

It is pretty standard practice to replace oil pan crush washers with each use. That said, I rarely replace them and have never had any leaks. They are cheap and easy to replace, but can be a hassle if you don't have one. Generally, nothing bad will happen, but they are designed to deform with each use, and at some point will not seal properly. This is why most manufacturers call for replacing them each time.

put me in the camp of always replacing the crush ring...they are so cheap...why not replace it...sometimes I get them thrown in for free when I buy the filter.

Almost not needed whatsoever IMHO, maybe after about 10 oil changes I would install a new one.

yes...

Only if you're one of those crazy people that follow the service manual and use a torque wrench. Otherwise, just trade it in every few years and let someone else spit out pieces of their broken luck!

Only when you find it in the drain pan after you have already installed the bolt with the new fluids...

I didn't think so and haven't used one in quite a few oil changes. The other day I found an oil lead from the drain plug. Got me a mess of crush washers, actually brass seal washers from McMaster Carr and installed with just a little loss of oil and the leak has stopped. Now I have enough for 150,000 miles

The term "crush washer" is incorrect. It is just a plain flat aluminum washer and you need to replace it only if you see a visible groove cut in it by the drain plug bolt head. This should not happen if you do not overtighten the drain plug.

A "crush washer" is one that actually flattens as you tighten the drain plug. Many Nissan vehicles have those. I have it on my Suzuki Bandit 1250S.

The aluminim washer on the drain plugs on C-14s really do 'crush' or deform. Mine are original and are now extruded enough that the washer does not turn or move against the screw, and it is getting a bit bigger in diameter too.

Nothing wrong with changing them but I have not done it yet and no leaks so far after something like 25 oil changes.

You only changed your oil twice in 52000 miles?

Heck, my first change was under a hundred miles on the odo, I used a coffee filter to see shat came out, lots of silver color for sure, I dumped the still good oil in the backhoe and some nice fresh Lucas full syn. I change the oil as soon as shifting starts feeling notchy or before a big trip. I also change after a hard day at the track, WFO, brakes and back to WFO. Repeat. Sometimes we even blow by the man made coned chicane at lunch time. Makes for some quick laps and gets the heart rate up there.

O, I use the Harley method, add as needed
